This study has been completed.

Antisoma Research Identifier:
First received: March 4, 2009
Last updated: NA
Last verified: March 2009
History: No changes posted
This was a phase I study aimed at identifying safe doses of DMXAA (now known as ASA404) to be used in future combination studies with chemotherapy.

Condition Intervention Phase
Refractory Tumors
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Crossover Assignment
Masking: Double Blind (Participant, Investigator)
Primary Purpose: Treatment
Official Title: 5,6-Dimethylxanthenone-4-Acetic Acid (DMXAA) in the Treatment of Refractory Tumors: A Phase I Multicentre Doubleblind Randomized Six-Way Intrapatient Dose-Ranging Crossover Safety Study.

Further study details as provided by Antisoma Research:

Primary Outcome Measures:
  • To identify a range of doses for DMXAA where there was either no effect or an acceptably small effect on QTc

Secondary Outcome Measures:
  • To investigate and describe the relationship between QTc prolongation, plasma levels of DMXAA and time from start of infusion.
  • To further investigate the safety profile of DMXAA
  • To further investigate the pharmacokinetic behaviour of DMXAA
  • To further characterise the ophthalmic effects of DMXAA
  • To document anti-tumour activity and/or clinical signs of efficacy in patients
  • To assess the effects of DMXAA on tumour blood flow using dynamic MRI

Enrollment: 15
Study Start Date: May 2003
Study Completion Date: January 2004
Primary Completion Date: January 2004 (Final data collection date for primary outcome measure)
Intervention Details:
    Drug: DMXAA
    DMXAA, given intravenously over 20 minutes. Patients were to each undergo six doses of treatment at weekly intervals, receiving each of six doses (300, 600, 1200, 1800, 2400 and 3000 mg/m2)
Detailed Description:

This was a multi-centre randomized, double blind study to further characterize the effect of DMXAA on QTc interval, ophthalmic safety and pharmacodynamic effects on tumour blood flow.

Patients with refractory tumors were to each undergo six doses of treatment at weekly intervals, receiving each of six doses of DMXAA (300, 600, 1200, 1800, 2400 and 3000 mg/m2)
